This is the face of Liam Degar, known as the Shadows' King to his enemies during a 50 year war on the planet of Krailmar. He fought on the side of the Drow, giving in to the blood rage of his evil Shadow lineage... In other words, he was a really mean cat, but now he's trying to make up for it by being the protector of one of the big good guys in the multiverse thing. Those little guys fighting above his head are his shoulder angel/demon. Y'know, his conscience. He can have lapses into his darker side in the heat of battle, so he's still battling and stuff.
